Benzodiazepine (Oxazepam)-BSA Antigen

Supplied by Antibodies.com, this ready-to-use hapten-carrier conjugate is engineered for immunoassay development targeting the benzodiazepine class of small molecules. Presented as a liquid Oxazepam-BSA antigen in 10 mM Phosphate Buffered Saline at pH 7.2, the conjugate is preserved with 0.01% sodium azide and shipped at a working concentration of approximately 5.0 mg/mL. The 1 mg pack size is designed as a coating or competitor antigen for ELISA and Lateral Flow (LF) assay platforms used in drugs-of-abuse testing and therapeutic drug monitoring workflows. Because the hapten is covalently linked through an active ether position to bovine serum albumin (BSA), the reagent pairs reliably with matched anti-benzodiazepine detection antibodies for competitive immunoassay formats, and it is also referenced as a capture antigen in several matched-pair configurations. The product is intended for research use only and is not validated for diagnostic or therapeutic applications. For handling, short-term storage at 2–8 °C is appropriate for up to two weeks, while long-term storage at −20 °C is recommended; users should avoid repeated freeze–thaw cycles to preserve immunoreactivity. The conjugate demonstrates broad class reactivity toward oxazepam and structurally related benzodiazepines, making it a versatile reagent for screening assays covering multiple analytes within this pharmacologic family.
